This healthy whole-grain buttermilk pancake recipe adds mini-chocolate chips and mashed banana to the 100% whole-wheat flour base. If you want to experiment with different types of whole grains, replace up to 1/2 cup of the whole-wheat flour with cornmeal, oats and/or buckwheat flour. Or add extra fiber and healthy omega-3 fats by adding up to 3 tablespoons of ground flaxseed or chia seeds.
